Still, from the point of view of the language string template parameters
are not necessarily lambdas. The fact that a particular template may mix
them in and use in similar fashion cannot change it.

Possibly but again, the language not necessarily knows what that string
means. The whitespace my be significant.

So-called "string lambdas" are actually pretty weird. You know that "e <
d" cannot work with SortedRange, right? The string is actually mixed-in;
so you have to know what the surrounding code expects and provide a
matching string. In this case, you have to provide 'a' and 'b'.
